Logan was said to have had a "hostile relationship" with his brother and searches of his computer found he had researched burn injuries.

The family dog, Gomez, was also killed in the fire.

Detective Superintendent Allan Burton,from Police Scotland’s Major Investigation Teams, said: “Today marks the end of an unusual and complex investigation which has left a family utterly devastated as a result of Blair Logan’s actions.

“A mother and father have lost both of their sons and a young woman has lost her partner, in a truly incomprehensible and tragic set of circumstances.

“This investigation involved a team of specialist officers that worked around the clock to piece together the events that led up to the fire being started on New Year’s morning, resulting in the death of Cameron Logan.

“This was undoubtedly a very distressful crime which took place right in the heart of Milngavie and the support of the local community, as well as the information provided by members of the public who were in the surrounding area that morning, were absolutely vital in helping us trace the person responsible.”

More than 200 people gathered to pay their respects to Cameron at his funeral in February.
